Titans is one of those shows which is iconic but suffers with hurried writting.
Don't get me wrong show is cool and character development is also good. Basically they build this whole idea of a supervillain throughout the whole show and the main protagonists(Titans) tend to stop them.
The built up is so good that you will fall in love with the show.
The only reason that this couldn't be 5 stars is how they deal with endings.
Like you establish a whole storyline for a supervillain and audience really starts to hate him, also either the supervillain shown is too smart or too powerful, but in the end they always die an easy death. Like whatsoever have no sense to use their power....
There are some scenes that might become boring but the length of episodes keep you so hooked and get you through an emotional rollercoaster.
Personally I liked the storyline of Garfield Logan and Dick Grayson. From all main protagonists. The best storyline was of the red hood that guy should've a spin off series imo.
Overall great show but loose endings.
